We stock a full line of ANSI one strand 304-grade stainless chain sprocket sprockets both as A-Plate style and B-Hub style. We maintain these on the shelf as regular stock bores. Nevertheless, we can supply sprockets with completed bores thanks to our fast-reaction in house industrial machine shop. Typically our sprockets are produced out of 304 grade stainless, but 316 in addition to a few other grades are available upon request.
